Traffic Light Signal Guide - Meaning of Red, Yellow, and Green Lights #3242390 (License: Personal Use)

This image depicts a standard vertical traffic signal housing three circular lamps: red on top, amber/yellow in the middle, and green at the bottom. Each light features concentric ripple detailing to simulate lens refraction and illumination intensity. Though all three are shown lit here-a configuration not used in real-world operation-it serves as a clear visual reference for color coding and signal layout.

Used on transportation safety pages, driver education materials, traffic regulation guides, or municipal websites explaining road signage. Matches user intent to understand traffic signal design, rules, or visual identification for licensing exams or public awareness.
